Day 40: Troubleshooting Internet Accessibility for an EC2-Hosted Application

Welcome to Day 40. Today, we will learn how to troubleshoot internet accessibility for an application hosted on EC2. When I try to access my EC2 instance's public IP via a browser, there is no response. I then check whether my EC2 instance's subnet is public or private. My instance is in a public subnet, but I still can't access my application from the internet. Then I checked the VPC settings and saw that my public subnet's route table was not connected to the Internet gateway. So, I went to the Internet gateway settings and saw that my Internet Gateway was not attached to the VPC. That's the main cause of the issue. After I attached my Internet Gateway to the VPC, I was able to access my application from the internet.
